In addition, the purchaser should anticipate the need for test batches or extra preparation steps, or both, such as blasting before galvanizing or other methods, to attempt to reach the higher requirements with consistency. NOTE 2—The presence in steels and weld asgm, in certain percentages, of some elements such as silicon, astj, and phosphorus tends to accelerate the growth of the zinc-iron alloy layer so that the coating may have a matte?

These designations often apply to specific products, for example A is applicable to cold-heading quality carbon steel wire for tapping or sheet metal screws. This shall be achieved by an in-plant inspection program designed to maintain the coating thickness,? Metallic coated carbon steel wire coated at size for mechanical springs Composite ribbed steel pipe, pre-coated and polyethylene lined sewer pipe application Flexible poly vinyl chloride PVC gaskets used in connection of water closets to sanitary drainage system For more information on the ASTM designation system see our related article: Lumps, projections, globules, or heavy deposits of zinc which will interfere with the intended use of the material will not be permitted.

ASTM Standard List: Coated Steels

Users of this standard are expressly advised that determination of the aetm of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. The result list consists of over ASTM metal standards.

For purposes of this speci? Except for local excess coating thickness which would interfere with the use of the product, or make it dangerous asm handle edge tears or spikesrejection for nonuniform coating shall be made only for plainly visible excess coating not related to design factors such as holes, joints, or axtm drainage problems see Note 6.


The elements can be added to the galvanizing bath as part of a pre-alloyed zinc feed, or they can be added to the bath by the galvanizer using a master feed atsm. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

The average of the? Individual reprints single or multiple copies asstm this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Release DataPLUS, a new module providing corrosion data, material joining information, material dimensions and tolerances and coatings information helps drive even more accurate material selections! The pieces shall be handled so that after galvanizing they will not freeze together on cooling.

Our mission is simple; to make Total Materia the one-stop place and first choice of engineers world wide. NOTE 3—The galvanizer may choose to add trace amounts of certain elements for example, aluminum, nickel, and tin to the zinc bath to help in the processing of certain reactive steels or to enhance the a86 appearance of the?

Total Materia has allowed us to solve in a definite way all problems we had for the search of alternate materials in foreign countries.

The zinc coating on threaded components of articles galvanized under this speci? Originally published as A — 28 T. NOTE 5—Inaccessible surface areas are those which cannot be reached for appropriate surface preparation and application of repair materials as described in Practice A Inspection, Rejection, and Retest 9. It is the responsibility of the purchaser to heat treat or otherwise allow for the possibility of such embrittling phenomena. Internal threads are not prohibited from being tapped or retapped after galvanizing.

The galvanizing of separate reinforcing steel bars shall be in accordance with Speci?

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. The galvanizer has only limited control over this condition. Coatings shall conform to the requirements of Speci?

The average of no less than? ASTM B standard spe If the lot size is such that the sample size cannot be doubled, then the sample size shall be as previous, but the number of widely dispersed sites at which measurements were made shall be doubled, and these sites will constitute the new sample.


The galvanizer shall afford the inspector all reasonable facilities to satisfy him that the zinc coating is being furnished in accordance with this speci? If a sample x386 taken as representing the lot for acceptance, the sample shall be taken at random from the lot without regard sstm the perceived quality or appearance of any individual unit in the lot being sampled.

In the case of any such local section containing more than one material category or steel thickness range 3a86 delineated in Table 1, that section will contain asttm than one specimen see Fig. This new sample shall be measured using magnetic thickness gages which have been calibrated for accuracy against reference material thickness standards.

NOTE 7—Items which zstm prepared for galvanizing by abrasive cleaning will generally develop a thicker coating with a a3886 rougher surface. To get started, click on the standard list button in the menu bar. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. In such case, the now-smaller lot shall be treated as a new lot for purposes of inspection and acceptance.

Within seconds it is also possible for you to find related detailed material property data or search equivalent materials starting from the Total Materia standard list. DataPLUS, a new a836 providing corrosion data, material joining information, material dimensions and tolerances and coatings information helps drive even more accurate material selections! Purchasers desiring a guarantee of heavier coatings than the minimum thicknesses shown herein should use the special requirements see 4.
